A "handful of people" will vote fraudulently??? Wow, you have way too much trust in people. I watch the news and see how many unethical/lying/law-breaking people are out there. Please show me some statistics that there is just a few people, here and there that vote illegally??? Can you give us any research or studies to back this?
I see what you are doing there. You have no evidence that it does exist, so you flip it around and ask for people to prove it doesn't. Except it's pretty much impossible to prove the lack of something that doesn't exist, so you then walk away feeling like you are proven right.
